Struct InviteSummary 

pub struct InviteSummary {
    pub user: Option<String>,
    pub display_name: Option<String>,
    pub grants: Vec<String>,
    pub expires_at: u64,
    pub issued_by: String,
}

What an invite promises its holder, read by the join page (D57).

A copy rather than a borrow: the store’s lock is released before the page is rendered, and rendering must not be able to hold it.

Deliberately not the whole stored invite: secret_hash has no business leaving the store, and issued_at says nothing a holder needs.

Fields

user: Option<String>

The account name redemption will create, when the issuer fixed one at minting.

None is the ordinary case (D75): an open seat, whose holder picks their own username on the page that redeems it.

display_name: Option<String>

Readable name the account will carry (D46), when the issuer set one.

grants: Vec<String>

The grants that account will be issued, as <repo> <level>.

expires_at: u64

Unix seconds after which the invite stops working.

issued_by: String

Who minted it, so the holder can see whether they know that name.
